FIFA 17 sends two different operations to `PUT …/squad/<id>` and distinguishes
them only by body shape. Across 73 captured squad PUTs in five captures there
are exactly two:
* 68x with `players` -- a full replacement (also carrying squadName,
formation, squadType, manager, chemistry/rating, and redundantly
captain/kicktakers);
* 5x without `players` -- `{id, custom, captain, kicktakers}`, emitted by the
captain/kick-taker screen.
`players` has `#[serde(default)]`, so an absent key and an explicit `[]`
collapsed to the same empty vec and every partial update was handed to Core as
a replacement with zero slots. Core's empty-replacement guard refused it (400)
and the host reported 502, losing the user's captain/kick-taker change.
`classify_squad_put` now tests key PRESENCE on the raw JSON before
deserialising, so absence ("the squad was not part of this edit") stays
distinct from an explicit empty array ("replace with nothing"). An explicit
`"players": []` still classifies as a replacement and still meets the guard --
the patch path is not a way around it.
The patch path carries the contract correction: omitted `players`, `manager`
and actives mean UNCHANGED, never cleared. That is structural --
`CoreRolePatchRequest` has no field able to express them. The extension is
MERGED rather than overwritten, because the partial body carries only `custom`
and `kicktakers`; overwriting would drop every kit number in the squad.
`custom` IS taken from the patch, since the role screen writes per-slot values
into it and the two shapes genuinely differ there.
Also fixes the error mapping on this route: a Core 400 means the REQUEST was
invalid, so it is reported as 400, not as a 502 that blames the server and
hides a client error behind "upstream unavailable".
Tests use the real captured body and assert it takes the patch path
(`replace_squad` call count unchanged), that the manager survives, that kit
numbers survive the merge, that an explicit empty `players` still reaches the
replacement path, and that an unresolvable captain refuses the whole patch
rather than half-applying the kick-takers.
Every real squad save was failing with 400 unresolved_wire_ids. Reproduced on
staging with the repo's own seeder, which sends the captured retail body:
route=squad-replace status=400 outcome=unresolved_wire_ids detail=[[100000427]]
FIFA 17 always sends a manager ref, and on a real profile it does not resolve to
an owned instance. scripts/sold-staging-seed-squad.py already recorded why:
production's own squad points at instance 100000427, which is absent from
production's /club/staff (1975 items spanning 100000001..100004826), and the
client accepts that squad back unchanged -- so the client never validates the
manager against the club, and the pre-0023 server accepted it.
Making the manager ownership-backed (d37a9d5 / 25f4ad1) turned that ref into a
hard refusal, which took out the primary FUT write path: no squad save means no
squad, which means the client will not enter the FUT hub at all.
A manager ref is not a squad slot. An unresolvable PLAYER slot must still refuse
the save -- committing it would silently drop an owned card from the club. An
unresolvable MANAGER ref just means there is no ownership-backed manager, which
is exactly the state before migration 0023: the save commits, the assignment is
cleared as a full replacement should, and the id is reported on
ProposedSquad::unresolved_manager_wire_id so the host can log what it could not
map instead of letting it vanish. A ref that DOES resolve is still assigned and
still authorized against the club.
Verified end to end on staging: the seeder now answers {"id": 0} with 11
occupied slots, the host logs
`manager_ref_unresolved=100000427 (saved with no manager assignment)`, and the
projected squad carries `manager: []`.
Move the squad manager from an opaque, unvalidated wire ref in the squad
extension to a resolved, ownership-backed assignment (Core migration 0023
squad_managers).
- squad::to_proposed reverse-resolves the manager wire ref to a Core
owned_card_id on ProposedSquad; an unresolvable manager is reported as
an unresolved wire id (a live save is refused rather than assigning a
manager the club does not own).
- squad_ext: drop the opaque manager field from Fifa17SquadExtensionV1
(clean cutover) and the now-unused SquadEntityRef->WireItemRef From.
- squad_projection: project the manager as the STATIC_REVERSED [{id,dream}]
wire ref resolved from the owned assignment; absent -> [] (never faked).
Richer manager itemData (contract/league/nation) is INFERRED-only and
left out pending wire reversal.
- import(apply): drop a historical dangling manager ref rather than
failing the whole import (live PUTs still refuse an unresolved manager).
Formatting-only. Runs the project formatter over the files authored/edited
this session (host lib+tests, adapter item/squad_ext/squad_projection/mod +
projection test). The intentionally-preserved dirty catalog.rs and
pre-existing /club-era host drift beyond these files are out of scope.
Add fut::squad_ext::Fifa17SquadExtensionV1 — the versioned, adapter-owned
payload Core stores opaquely alongside the canonical squad. Carries the
FIFA-only wire state that is not Core-canonical:
- custom[] opaque 33-int string, round-tripped verbatim
- squad_type observed FIFA token
- kit_numbers keyed by owned_card_id (kit follows the PLAYER, proven
by the swap/formation captures), never by slot/definition
- manager opaque item ref (not a squad player; not shaped)
- kicktakers opaque role refs; relationship to captain UNKNOWN, so
preserved verbatim and never normalized to the captain
- client_reported chemistry/rating/starRating shadow, never authoritative
from_payload enforces the payload schema version first (distinct from Core's
DB schema); an unknown version is rejected, never coerced.
build_squad_write turns a parsed PUT + host wire->owned resolver into a
canonical ProposedSquad + extension, refusing on unresolved ids or a
duplicate owned item. Identity resolution is explicitly NOT authorization.
Refactor the 550a59d parser scaffold: ProposedSquad is now pure canonical
(FIFA-only + shadow fields moved to the extension); the canonical formation
is the FIFA wire token verbatim (drop the lossy f442->"4-4-2" map that
could not even represent f433) so formation and index round-trip exactly
with no derivation. Bench split is the fixed 23-slot array convention.
